The default shall be the current directory. The +.BR \(mid +option shall take precedence over the +.IR PROJECTDIR +variable. See +.BR \(mip . +.IP "\fB\(mip\ \fIpath\fR" 10 +A pathname of a directory in which the SCCS files are located. The +default shall be the +.BR SCCS +directory. +.RS 10 +.P +The +.BR \(mip +option differs from the +.BR \(mid +option in that the +.BR \(mid +option-argument shall be prefixed to the entire pathname and the +.BR \(mip +option-argument shall be inserted before the final component of the +pathname.

The +intent is to have this included in an ``install'' entry in a makefile +to ensure that everything is included into the SCCS file before a +version is installed. +.IP "\fBclean\fR" 8 +Remove everything from the current directory that can be recreated from +SCCS files, but do not remove any files being edited. If the +.BR \(mib +option is given, branches shall be ignored in the determination of +whether they are being edited; this is dangerous if branches are kept +in the same directory. +.IP "\fBcreate\fR" 8 +Create an SCCS file, taking the initial contents from the file of the +same name. Any options to +.IR admin +are accepted. If the creation is successful, the original files shall +be renamed by prefixing the basenames with a comma. These renamed files +should be removed after it has been verified that the SCCS files have +been created successfully. +.IP "\fBdelget\fR" 8 +Perform a +.IR delta +on the named files and then +.IR get +new versions.

This option is useful for making a checkpoint of the current +editing phase. The same options shall be passed to +.IR delta +as described above, and all the options listed for +.IR get +above except +.BR \(mie +shall be passed to +.BR edit . +.IP "\fBdiffs\fR" 8 +Write a difference listing between the current version of the files +checked out for editing and the versions in SCCS format. Any +.BR \(mir , +.BR \(mic , +.BR \(mii , +.BR \(mix , +and +.BR \(mit +options shall be passed to +.IR get ; +any +.BR \(mil , +.BR \(mis , +.BR \(mie , +.BR \(mif , +.BR \(mih , +and +.BR \(mib +options shall be passed to +.IR diff . +A +.BR \(miC +option shall be passed to +.IR diff +as +.BR \(mic . +.IP "\fBedit\fR" 8 +Equivalent to +.IR get +.BR \(mie . +.IP "\fBfix\fR" 8 +Remove the named delta, but leave a copy of the delta with the changes +that were in it. It is useful for fixing small compiler bugs, and so +on. The application shall ensure that it is followed by a +.BR \(mir +.IR SID +option. Since +.BR fix +does not leave audit trails, it should be used carefully. +.IP "\fBinfo\fR" 8 +Write a listing of all files being edited. If the +.BR \(mib +option is given, branches (that is, SIDs with two or fewer components) +shall be ignored. If a +.BR \(miu +.IR user +option is given, then only files being edited by the named user shall +be listed. A +.BR \(miU +option shall be equivalent to +.BR \(miu <\c +.IR "current\ user" >. +.IP "\fBprint\fR" 8 +Write out verbose information about the named files, equivalent to +.IR sccs +.IR prs . +.IP "\fBtell\fR" 8 +Write a +<newline>-separated +list of the files being edited to standard output. Takes the +.BR \(mib , +.BR \(miu , +and +.BR \(miU +options like +.BR info +and +.BR check . +.IP "\fBunedit\fR" 8 +This is the opposite of an +.BR edit +or a +.IR get +.BR \(mie . +It should be used with caution, since any changes made since the +.IR get +are lost. +.br +.SH "EXIT STATUS" +The following exit values shall be returned: +.IP "\00" 6 +Successful completion. +.IP >0 6 +An error occurred. +.SH "CONSEQUENCES OF ERRORS" +Default. +.LP +.IR "The following sections are informative." +.SH "APPLICATION USAGE" +Many of the SCCS utilities take directory names as operands as well as +specific filenames.
